  • DETAILED DESCRIPTION
  • The subject disclosure describes, among other things, illustrative embodiments of a server and a method for scheduling transmission of data (e.g. data packets for presentation of media content) to a client device. In one or more embodiments, data transmissions over a network, in fulfillment of requests received from a mobile device communicatively coupled to the network, can be managed (e.g., scheduled and/or rescheduled) according to various factors, such as one or more of predicted power states of a mobile device, network performance characteristics, historical network data, and so forth. In one or more embodiments, the performance characteristics can be used for predicting future characteristics of a network. In one embodiment, some or all of the future characteristics can be predicted for network segments of a network where the network segments are portions of the network along, or otherwise associated with, a trajectory of the mobile device. The future characteristics can include future transport characteristics (e.g., predicted network traffic, predicted jitter, predicted available bandwidth, and so forth) and/or future segment characteristics (e.g., future availability of network elements of the network segments).
  • In one or more embodiments, the predicted future power state of a mobile device can be based on monitoring of power state transitions of the mobile device. In one or more embodiments, a transition between a high-power state and a low-power state is predicted based on a first elapsed time from receiving another transmission request or a second elapsed time from transmitting a second data packet. In one or more embodiments, the performance characteristics can include historical performance data indexed by a time of day. In one or more embodiments, location information and movement information for the mobile device are obtained by monitoring communication with the mobile device, and the trajectory of the mobile device is determined based on the location information and the movement information. In one or more embodiments, a target time for fulfilling a transmission request can be determined based on reducing a degradation in a viewing quality of media content to be displayed by the mobile device, where the trajectory of the mobile device is on a path having network elements that provide varying transmission rates to the mobile device.
  • Other embodiments are included in the subject disclosure.
  • The exemplary embodiments described herein are related to, and can be combined with or replaced by, methods and/or components described in U.S. application Ser. No. 14/092,092, entitled “CLIENT-SIDE SCHEDULING FOR MEDIA TRANSMISSIONS ACCORDING TO CLIENT DEVICE STATES” and having attorney docket no. 2013-10387785-1036, the disclosure of which is hereby incorporated by reference.
  • One embodiment of the subject disclosure includes a system having a memory to store instructions and a controller coupled to the memory. The controller, responsive to executing the instructions, can perform operations including obtaining performance characteristics for network segments of a network. The network segments can be selected from a group of network segments based on a trajectory of a mobile device communicatively coupled to the network. The controller can predict a future transport characteristic and a future segment characteristic for the network segments based on the performance characteristics. The future segment characteristic may not be associated with a non-selected network segment of the group of network segments. The controller can receive a request from the mobile device for transmission of a data packet over the network. The controller can predict a future power state of the mobile device, based on monitoring information for a power state of the mobile device. The controller can determine a target time for fulfilling the request. The target time can be determined based on the future power state of the mobile device, the future transport characteristic and the future segment characteristic. The controller can schedule a time for fulfilling the request according to the target time.
  • One embodiment of the subject disclosure includes a computer-readable storage device comprising executable instructions which, responsive to being executed by a processor of a server, cause the processor to perform operations including obtaining performance characteristics of network segments of a network. The network segments can be selected from a group of network segments of the network, based on a trajectory of a mobile device communicatively coupled to the network. The operations can include monitoring power state transitions of the mobile device and predicting a future power state of the mobile device based on the monitoring of the power state transitions. The operations can include determining a target time for fulfilling a request for transmission of a data packet to the mobile device over the network. The target time can be determined based on the performance characteristics for the network segments and the future power state of the mobile device. The operations can include scheduling a time for fulfilling the request according to the target time.
  • One embodiment of the subject disclosure is a method including monitoring, by a server comprising a processor, performance characteristics of network segments of a network. The network segments can be selected from a group of network segments of the network, based on a trajectory of a mobile device communicatively coupled to the network. The method can include monitoring, by the server, power state transitions of the mobile device. The method can include predicting, by the server, a future power state of the mobile device based on the monitoring of the power state transitions. The predicting of the future power state can be based on determining a first elapsed time from receiving a first request from the mobile device for transmission or a second elapsed time from transmitting a first data packet. The method can include determining, by the server, a target time for transmission of a second data packet over the network. The target time can be determined based on the performance characteristics for the network segments and based on the future power state of the mobile device. The method can include scheduling, by the server, a time for transmission of the second data packet according to the target time.
  • FIG. 1 schematically illustrates an architecture 100 for a cellular network. Mobile devices 110 can be various types of devices such as smartphones, tablets, laptops, vehicle communication systems, and so forth. The mobile devices 110 can establish an end-to-end connection established with either a Public Switched Telephone Network (PSTN) 160, in the case of voice traffic, or an internet protocol network (Internet) 102, in the case of data traffic. As shown schematically in FIG. 1, a given mobile device can move through geographic regions having different and sometimes overlapping networks with different characteristics. A mobile device accesses a network by connecting with a base station 115 belonging to that network. As shown in FIG. 1, the architecture 100 can include a Global System for Mobile Communications (GSM) network 120, a 3G network 130, and/or a Long Term Evolution (LTE) network 140. In particular, LTE specifications define an all-internet protocol architecture with voice over internet protocol (VoIP). FIG. 1 also illustrates a device accessing the network through an Internet Service Provider (ISP) broadband connection 112.
  • In general, a mobile device 110 that is in motion can connect with a variety of networks, or network segments of a network, and therefore receive and transmit data at different rates at different times. A network segment, as described in the exemplary embodiments, can be a portion of a network which is defined or otherwise designated based on various criteria, such as a network segment falling between particular network nodes or network elements, a network segment having a particular geographic area and/or shape, a network segment with a service region based on a particular set of network devices, and so forth. The number and configuration of the network segments making up a particular network can vary. Additionally, network segments can vary over time, such as two network segments merging into a single network segment in response to particular network devices in the network segments going offline. In the architecture 100, a network (e.g., LTE network 140) can be intermittently available at a given location.
  • According to an embodiment of the disclosure, a Dynamic Adaptive Streaming over HTTP (DASH) compliant server monitors power states of a client device communicatively coupled to the server via a network. As shown schematically in FIG. 2, a DASH-compliant server 201 communicates with a mobile client device 211 by a network 210 in a system 200. The server 201 monitors an individual network connection between network 210 and the client device 211 while the client device 211 moves from one location to another (e.g. along path 250 from a starting point 251 to an ending point 252). The server 201 receives requests for media segments (segments of media content—for example, packets of video data) from the client device 211.
  • As shown in FIG. 2, system 200 comprises a server and one or more clients, where a server is a device that manages requests for those clients. These clients may be endpoint devices that include the functionality of displaying video for users. However, in another embodiment of the disclosure, there is an intermediary between the server and the endpoint device. This intermediary acts as a client of the first server, but it acts as a server to the endpoint client and can be called a proxy server. Further, a number of proxy servers may be connected in to a network and any particular transmission of data from server to client may pass through more than one proxy server. Advantageously, endpoint clients can implement a fully standard and simplified data packet reception function whereas the proxy servers may implement an additional function that incorporates information about the network and is used to route data requests to proxy servers to provide for more efficient network link utilization. The particular route or set of proxy servers traversed may change during the playback of a media stream so that different packets of a particular media stream may travel along different routes. The terms “server” and “system” as used herein are intended to include proxy servers. Further, a server is understood to include a cellular base station. Additionally, a mobile device such as a smartphone may act as a server, for example when it is serving as a mobile hot spot (e.g., providing WiFi network connectivity for endpoint devices).
  • In this embodiment, the client device 211 has three power states 231: off, low-power and high-power. The client device 211 follows a power control procedure in which state transitions are controlled based on the current state, the time elapsed since the last change of state, and requests for media segments transmitted to the server 201.
  • Based on awareness of network performance and awareness of the power states of the client device 211, the server 201 can alter its schedule for transmitting requested media segments. FIG. 3 illustrates a time sequence 300 in which the mobile client device 211 executes state transitions, and in which the schedule for fulfillment of media requests by the server 201 is altered in response to an anticipated change of state. In the example of FIG. 3, mobile client device 211 moves from the low-power state to the high-power state at time 321. The server monitors communications from the client device, and is aware that a lack of new requests from the client device for data transport will result in a state change back to the low-power state after an elapsed time (e.g. 3 seconds after the last change of state). The server determines that the power state of the mobile device will be moved from high-power to low-power at time 323 (in this example, time 323 is 3 seconds after time 321). The server then reschedules a transmission of a media segment from time 322 to time 324 (which is prior to time 323), so that the client device 211 can receive the transmission while avoiding the delay and power consumption incurred in changing states.
  • FIG. 4 is a flowchart illustrating a procedure 400 for server-side scheduling of transmission of media segments to a client device based on power state transitions of the client device, in accordance with an embodiment of the disclosure. A DASH-compliant server (e.g. server 201 shown in FIG. 2) monitors a network and monitors power states and state transitions in a client device communicatively coupled to the server via the network. (step 402). The server receives a request from the client device for a media segment (step 404), and then schedules transmission of the media segment to the client device (step 406). The server determines whether the client device is in the high-power state (step 408). If the client device is in the low-power state, the server will transmit the media segment at the scheduled time (step 414). (In this embodiment, transmitting the media segment instigates a transition to the high-power state so that the client device can receive and process the media segment.) If the client device is in the high-power state, the server determines (step 410) whether an anticipated transition to the low-power state will occur before the scheduled transmission. If so, the server reschedules the transmission of the media segment (step 412) so that the client device can receive the media segment while in the high-power state, and thus avoid having to perform another power state transition. The server selects a transmission rate for transmission of the media segment to the mobile device (step 414), responsive to detecting the time for fulfilling the request. The media segment is then transmitted at the scheduled (or rescheduled) time using the dynamic adaptive streaming over hypertext transfer protocol (step 416).
  • According to another embodiment of the disclosure, shown schematically in FIG. 5, network performance in a system 500 can be evaluated by measuring traffic, delays, jitter, throughput or a combination thereof. In this embodiment, an additional server function evaluates characteristics of network segments (wired segment, wireless segment, etc.) which can provide information regarding network performance. In some embodiments, network performance is described in terms of network throughput, but the disclosure is not so limited.
  • The server 501 can monitor an individual network connection (for example, a connection between network 510 and a client device 511) or monitor aggregated network transport data. The server 501 receives requests for media segments (segments of media content—for example, packets of video data) from the client device 511 via the network 510. The server 501 can alter the service time for video packet requests based on information about the transport characteristics.
  • In an embodiment, the individual network connection with the client device 511 is monitored while the client device 511 moves from one location to another (e.g. along a path 550 from a starting point 551 to an ending point 552). The performance of the network with respect to the client device 511 can vary with movement of the device. The server 501 can predict a future location of the client device 511 based on a current location and the trajectory of the client device 511. Server 501 can estimate network performance based on anticipated motion of the client device for some period of time referred to as the look-ahead time.
  • Based on awareness of network performance and awareness of the trajectory of the client device 511, the server 501 can alter its schedule for transmitting requested media segments. For example, as shown schematically in FIG. 5, when the client device 511 is at location 561, the server 501 can predict that the client device will enter a hotspot 580 where network performance better than in the current location is available, including a higher packet transmission rate. The server 501 can delay transmission of a requested media segment to client device 511 until client device 511 has entered the hotspot 580.
  • FIG. 6 is a flowchart showing a procedure 600 for server-side scheduling of media transmissions, in accordance with an embodiment of the disclosure. The network is monitored (step 602) to obtain information regarding the network throughput. In an embodiment, this can be done by monitoring an individual connection (a particular DASH session). In an alternative embodiment, the server may monitor the rate at which media requests arrive as part of a standard DASH session and infer information about the network throughput. In yet another embodiment, information regarding network throughput can be determined based on engineering designs of the deployed network between the client and the server. As shown schematically in FIG. 6, network intelligence (also termed network awareness) resides with the server 501.
  • Network throughput at a future time can be inferred based on an anticipated trajectory of a moving mobile client device. If the client device is mobile (step 604), the server can use the movement history (including the current location) of the client device and its trajectory (step 606) to predict a future location of the client device (step 608). The future network throughput is predicted based on the predicted location (step 610). In the case of a mobile client device, historical network throughput data for the particular time of day and day of week or year can also be used to estimate network performance. Alternatively, dynamically updated network throughput information can be derived by monitoring performance of data transport sessions that are moving with similar trajectories coincident with the client device in question.
  • The server receives requests for media segments (step 612) from the client device. Network throughput will typically vary with time and/or the location of the client device. The server's schedule for providing media segments is altered accordingly (step 614).
  • The location of a moving client device can be predicted for some time in the future (look-ahead time). It will be appreciated that the look-ahead time depends on several factors, including (for example) buffering and file sizes at the server and the speed of the moving device.
  • In the embodiments described with reference to FIG. 6, the server can alter its schedule to increase its request processing time (that is, delay processing of requests). In another embodiment, network performance can be improved by offering alternative bit-rate representations of media segments at the server. FIG. 7 is a flowchart illustrating a procedure for altering the bit-rate representation of a media segment. In step 702, the server obtains information regarding a present (or predicted) network throughput. The server receives a request (step 704) for a media segment with a specified bitrate. The server determines (step 706) whether the throughput is (or will be) adequate to support presentation of the requested media segment. If not, the server prepares a compressed version of the media segment (step 708) and replaces the segment with the compressed version (step 710). The compressed version is then sent to the client (step 712) to fulfill the request.
  • For example, if the client device is moving through a region where network throughput is low, the client device may request a low-bitrate encoded segment. However, the server may determine that the requested representation still would not be at a bitrate low enough to support the uninterrupted playback of the video, given the information that the server has been able to obtain about the network throughput. The server may then replace the segment with a more compressed version of the media segment. Preparation of the media segments can be done dynamically, or in anticipation of the client device moving into a region where network performance is known to be worse than at the current location.
  • FIG. 8 is a flowchart showing a procedure 800 wherein the network intelligence (network awareness) is moved from the server to the client device. In an embodiment, the client obtains information regarding the network (step 802). If the client device is mobile (step 804), the client device can use its movement history (including the current location) and its trajectory (step 806) to predict a future location for the client device (step 808). The future network throughput is predicted based on the predicted location (step 810). In this embodiment, the client device has location awareness in addition to network awareness.
  • The client device then alters its requests for media segments according to the updated network throughput (step 812). If the anticipated throughput is lower than the current throughput, the client device can request additional segments and buffer them in order to support continuous playback (step 814). For example, if a user (carrying a client device) in a car is headed toward a region of low throughput, the client device can request a larger-than-normal number of media packets (at a lower-than-normal bitrate in order to keep the average bitrate reasonably constant) and buffer those media packets locally such that the media will continue to play as the car moves across the region. It will be appreciated that obtaining segments of media content before they are needed for presentation and buffering those segments permits uninterrupted delivery of the media content, particularly in situations involving heterogeneous networks—that is, where the device must communicate with several different networks of varying characteristics to obtain and present a media program.
  • FIG. 9 depicts an illustrative embodiment of a communication system 900 for delivering media content. The communication system 900 can represent an Internet Protocol Television (IPTV) media system. Communication system 900 can be overlaid or operably coupled with the system 200 as another representative embodiment of communication system 900. As detailed below, the system 900 comprises a memory to store executable instructions that can be executed by a controller coupled to the memory. The controller, responsive to executing the instructions, can perform operations. The operations include obtaining (e.g. by a server 930) performance characteristics for network segments of a network. The network segments can be selected from a group of network segments based on a trajectory of a mobile device communicatively coupled to the network (e.g. a trajectory of mobile device 916 moving between segments of network 917). The controller can predict a future transport characteristic and a future segment characteristic for the network segments based on the performance characteristics. The future segment characteristic may not be associated with a non-selected network segment of the group of network segments. The controller can receive a request from the mobile device for transmission of a data packet over the network. The controller can predict a future power state of the mobile device, based on monitoring information for a power state of the mobile device. The controller can determine a target time for fulfilling the request. The target time can be determined based on the future power state of the mobile device, the future transport characteristic and the future segment characteristic. The controller can schedule a time for fulfilling the request according to the target time.
  • The IPTV media system can include a super head-end office (SHO) 910 with at least one super headend office server (SHS) 911 which receives media content from satellite and/or terrestrial communication systems. Media content can represent, for example, audio content, moving image content such as 2D or 3D videos, video games, virtual reality content, still image content, and combinations thereof. The SHS server 911 can forward packets associated with the media content to one or more video head-end servers (VHS) 914 via a network of video head-end offices (VHO) 912 according to a multicast communication protocol.
  • The VHS 914 can distribute multimedia broadcast content via an access network 918 to commercial and/or residential buildings 902 housing a gateway 904 (such as a residential or commercial gateway). The access network 918 can represent a group of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provide broadband services over fiber optical links or copper twisted pairs 919 to buildings 902. The gateway 904 can use communication technology to distribute broadcast signals to media processors 906 such as Set-Top Boxes (STBs) which in turn present broadcast channels to media devices 908 such as computers or television sets managed in some instances by a media controller 907 (such as an infrared or RF remote controller).
  • The gateway 904, the media processors 906, and media devices 908 can utilize tethered communication technologies (such as coaxial, powerline or phone line wiring) or can operate over a wireless access protocol such as Wireless Fidelity (WiFi), Bluetooth®, Zigbee®, or other present or next generation local or personal area wireless network technologies (Bluetooth® and ZigBee® are trademarks registered by the Bluetooth Special Interest Group and the ZigBee Alliance, respectively). By way of these interfaces, unicast communications can also be invoked between the media processors 906 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.
  • A satellite broadcast television system 929 can be used in the media system of FIG. 9. The satellite broadcast television system can be overlaid, operably coupled with, or replace the IPTV system as another representative embodiment of communication system 900. In this embodiment, signals transmitted by a satellite 915 that include media content can be received by a satellite dish receiver 931 coupled to the building 902. Modulated signals received by the satellite dish receiver 931 can be transferred to the media processors 906 for demodulating, decoding, encoding, and/or distributing broadcast channels to the media devices 908. The media processors 906 can be equipped with a broadband port to an Internet Service Provider (ISP) network 932 to enable interactive services such as VoD and EPG as described above.
  • In yet another embodiment, an analog or digital cable broadcast distribution system such as a cable TV system 933 can be overlaid, operably coupled with, or replace the IPTV system and/or the satellite TV system as another representative embodiment of the communication system 900. In this embodiment, the cable TV system 933 can provide Internet, telephony, and interactive media services.
  • The subject disclosure can apply to other present or next generation over-the-air and/or landline media content services systems.
  • Some of the network elements of the IPTV media system can be coupled to one or more computing devices 930, a portion of which can operate as a web server for providing web portal services over the ISP network 932 to wireline media devices 908 or wireless communication devices 916.
  • Communication system 900 can also provide for all or a portion of the computing devices 930 to use computing and communication technology to perform server-side scheduling, which can include among other things, fulfilling requests for media segments in accordance with network characteristics (e.g. network throughput). The media processors 906 and wireless communication devices 916 can be provisioned with software functions to utilize the services of server 930.
  • Multiple forms of media services can be offered to media devices over landline technologies such as those described above. Additionally, media services can be offered to media devices by way of a wireless access base station 917 operating according to wireless access protocols, such as Global System for Mobile or GSM, Code Division Multiple Access or CDMA, Time Division Multiple Access or TDMA, Universal Mobile Telecommunications or UMTS, World interoperability for Microwave or WiMAX, Software Defined Radio or SDR, Long Term Evolution or LTE, and so on. Other present and next generation wide area wireless access network technologies can be used in one or more embodiments of the subject disclosure.
  • FIG. 10 depicts an illustrative embodiment of a communication system 1000 employing an IP Multimedia Subsystem (IMS) network architecture to facilitate the combined services of circuit-switched and packet-switched systems. Communication system 1000 can be overlaid or operably coupled with system 200 and communication system 900 as another representative embodiment of communication system 900. In particular, communication system 1000 can be configured to perform a method including monitoring, by a server comprising a processor, performance characteristics of network segments of a network. The network segments can be selected from a group of network segments of the network, based on a trajectory of a mobile device communicatively coupled to the network. The method can include monitoring, by the server, power state transitions of the mobile device. The method can include predicting, by the server, a future power state of the mobile device based on the monitoring of the power state transitions. The predicting of the future power state can be based on determining a first elapsed time from receiving a first request from the mobile device for transmission or a second elapsed time from transmitting a first data packet. The method can include determining, by the server, a target time for transmission of a second data packet over the network. The target time can be determined based on the performance characteristics for the network segments and based on the future power state of the mobile device. The method can include scheduling, by the server, a time for transmission of the second data packet according to the target time.
  • Communication system 1000 can comprise a Home Subscriber Server (HSS) 1040, a tElephone NUmber Mapping (ENUM) server 1035, a management server 1030, and other network elements of an IMS network 1050. The IMS network 1050 can establish communications between IMS-compliant communication devices (CDs) 1001, 1002, Public Switched Telephone Network (PSTN) CDs 1003, and combinations thereof by way of a Media Gateway Control Function (MGCF) 1020 coupled to a PSTN network 1060. The MGCF 1020 need not be used when a communication session involves IMS CD to IMS CD communications. A communication session involving at least one PSTN CD may utilize the MGCF 1020.
  • IMS CDs 1001, 1002 can register with the IMS network 1050 by contacting a Proxy Call Session Control Function (P-CSCF) which communicates with an interrogating CSCF (I-CSCF), which in turn, communicates with a Serving CSCF (S-CSCF) to register the CDs with the HSS 1040. To initiate a communication session between CDs, an originating IMS CD 1001 can submit a Session Initiation Protocol (SIP INVITE) message to an originating P-CSCF 1004 which communicates with a corresponding originating S-CSCF 1006. The originating S-CSCF 1006 can submit the SIP INVITE message to one or more application servers (ASs) 1017 that can provide a variety of services to IMS subscribers.
  • For example, the application servers 1017 can be used to perform originating call feature treatment functions on the calling party number received by the originating S-CSCF 1006 in the SIP INVITE message. Originating treatment functions can include determining whether the calling party number has international calling services, call ID blocking, calling name blocking, 7-digit dialing, and/or is requesting special telephony features (e.g., *72 forward calls, *73 cancel call forwarding, *67 for caller ID blocking, and so on). Based on initial filter criteria (iFCs) in a subscriber profile associated with a CD, one or more application servers may be invoked to provide various call originating feature services.
  • Additionally, the originating S-CSCF 1006 can submit queries to the ENUM system 1035 to translate an E.164 telephone number in the SIP INVITE message to a SIP Uniform Resource Identifier (URI) if the terminating communication device is IMS-compliant. The SIP URI can be used by an Interrogating CSCF (I-CSCF) 1007 to submit a query to the HSS 1040 to identify a terminating S-CSCF 1014 associated with a terminating IMS CD such as reference 1002. Once identified, the I-CSCF 1007 can submit the SIP INVITE message to the terminating S-CSCF 1014. The terminating S-CSCF 1014 can then identify a terminating P-CSCF 1016 associated with the terminating CD 1002. The P-CSCF 1016 may then signal the CD 1002 to establish Voice over Internet Protocol (VoIP) communication services, thereby enabling the calling and called parties to engage in voice and/or data communications. Based on the iFCs in the subscriber profile, one or more application servers may be invoked to provide various call terminating feature services, such as call forwarding, do not disturb, music tones, simultaneous ringing, sequential ringing, etc.
  • In some instances the aforementioned communication process is symmetrical. Accordingly, the terms “originating” and “terminating” in FIG. 10 may be interchangeable. It is further noted that communication system 1000 can be adapted to support video conferencing. In addition, communication system 1000 can be adapted to provide the IMS CDs 1001, 1002 with the multimedia and Internet services of communication system 900 of FIG. 9.
  • If the terminating communication device is instead a PSTN CD such as CD 1003 (in instances where the cellular phone only supports circuit-switched voice communications), the ENUM system 1035 can respond with an unsuccessful address resolution which can cause the originating S-CSCF 1006 to forward the call to the MGCF 1020 via a Breakout Gateway Control Function (BGCF) 1019. The MGCF 1020 can then initiate the call to the terminating PSTN CD over the PSTN network 1060 to enable the calling and called parties to engage in voice and/or data communications.
  • It is further appreciated that the CDs of FIG. 10 can operate as wireline or wireless devices. For example, the CDs of FIG. 10 can be communicatively coupled to a cellular base station 1021, a femtocell, a WiFi router, a Digital Enhanced Cordless Telecommunications (DECT) base unit, or another suitable wireless access unit to establish communications with the IMS network 1050 of FIG. 10. The cellular access base station 1021 can operate according to common wireless access protocols such as GSM, CDMA, TDMA, UMTS, WiMax, SDR, LTE, and so on. Other present and next generation wireless network technologies can be used by one or more embodiments of the subject disclosure. Accordingly, multiple wireline and wireless communication technologies can be used by the CDs of FIG. 10.
  • Cellular phones supporting LTE can support packet-switched voice and packet-switched data communications and thus may operate as IMS-compliant mobile devices 1022. In this embodiment, the cellular base station 1021 may communicate directly with the IMS network 1050 as shown by the arrow connecting the cellular base station 1021 and the P-CSCF 1016.
  • Alternative forms of a CSCF can operate in a device, system, component, or other form of centralized or distributed hardware and/or software. Indeed, a respective CSCF may be embodied as a respective CSCF system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective CSCF. Likewise, other functions, servers and computers described herein, including but not limited to, the HSS, the ENUM server, the BGCF, and the MGCF, can be embodied in a respective system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective function, server, or computer.
  • The server 930 of FIG. 9 can be operably coupled to the second communication system 1000 for purposes similar to those described above. Server 930 can perform server-side scheduling and thereby provide media transmissions to the CDs 1001, 1002 and 1003 of FIG. 10. Server 930 can be an integral part of the application server(s) 1017, which can be adapted to the operations of the IMS network 1050.
  • For illustration purposes only, the terms S-CSCF, P-CSCF, I-CSCF, and so on, can be server devices, but may be referred to in the subject disclosure without the word “server.” It is also understood that any form of a CSCF server can operate in a device, system, component, or other form of centralized or distributed hardware and software. It is further noted that these terms and other terms such as DIAMETER commands are terms can include features, methodologies, and/or fields that may be described in whole or in part by standards bodies such as 3rd Generation Partnership Project (3GPP). It is further noted that some or all embodiments of the subject disclosure may in whole or in part modify, supplement, or otherwise supersede final or proposed standards published and promulgated by 3GPP.
  • FIG. 11 depicts an illustrative embodiment of a web portal 1102 which can be hosted by server applications operating from the computing devices 930 of the communication system 900 illustrated in FIG. 9. Communication system 1100 can be overlaid or operably coupled with communication system 900 as another representative embodiment of the disclosure.

The target time can be determined based on the performance characteristics for the network segments and the future power state of the mobile device. The operations can include scheduling a time for fulfilling the request according to the target time.
  • The web portal 1102 can be used for managing services of communication systems 900-1000. A web page of the web portal 1102 can be accessed by a Uniform Resource Locator (URL) with an Internet browser using an Internet-capable communication device such as those described in FIGS. 1-2.

The web portal 1102 can also be used for provisioning IMS services described earlier, provisioning Internet services, provisioning cellular phone services, and so on.
  • FIG. 12 depicts an illustrative embodiment of a communication device 1200. Communication device 1200 can serve in whole or in part as an illustrative embodiment of the devices depicted in FIGS. 1-2 and FIGS. 9-10.
